How Long does it take for a dratini to grow to lv55 in a daycare?

In Pokémon games, the experience points required for a Dratini to reach level 55 from level 1 is approximately 1,250,000 XP. In the Day Care, Pokémon gain experience at a rate of 1 XP per step taken by the player. Since players typically take around 2,000 to 3,000 steps per hour, it can take several hours of gameplay, often exceeding 25-30 hours, to reach level 55, depending on various factors like the use of experience-boosting items or the number of Pokémon in the Day Care.
